1.2 For the installer
The precautions described in this document cover very important
topics, follow them carefully.
INFORMATION
This user interface is an option and cannot be used
standalone. It can ONLY be used in combination with a
main user interface. Also see the installation and operation
manual of the indoor and outdoor units.
NOTICE
Improper installation or attachment of equipment or
accessories could result in electric shock, short-circuit,
leaks, fire or other damage to the equipment. Only use
accessories, optional equipment and spare parts made or
approved by Daikin.
WARNING
All field wiring and components MUST be installed by a
licensed electrician and MUST comply with the applicable
legislation.
NOTICE
The user interface MUST be mounted indoors.
NOTICE
When the user interface is used as room thermostat, select
an installation location where the average temperature in
the room can be detected.
Do NOT install the user interface in the following places:
▪ In places that are exposed to direct sunlight.
▪ In places that are near a heat source.
▪ In places that are affected by outside air or air draught due to e.g.
door opening/closing.
▪ In places where the display can easily get dirty.
▪ In places where there is NO easy access to the controls.
▪ In places with temperatures <–10°C and >50°C.
▪ In places where the relative humidity is >95%.
▪ In places where there is machinery that emits electromagnetic
waves. Electromagnetic waves may disturb the control system,
and cause malfunction of the equipment.
▪ In places where it may be exposed to water, or in generally moist
areas.
If you are NOT sure how to install or operate the unit, contact your
dealer.
After finishing installation:
▪ Conduct a trial operation to check for faults.
▪ Explain the user how to operate the user interface.
▪ Ask the user to store the manual for future reference.

12.2.1 About space heating/cooling control
Space heating/cooling control involves:
▪ Controlling the room temperature;
▪ Setting the space operation mode.
Room temperature
Room temperature control is performed from the home screen. The
home screen displays the actual room temperature, as measured by
a temperature sensor mounted in the user interface. For instructions
on how to change the room temperature, see "12.2.3To change the
room temperature"on page14.
The way you control the room temperature depends on the
temperature control method that is set on the main user interface.

13.3 Software update
13.3.1 About software updates
It is strongly recommended that the user interface has the latest
software version. There are two ways to perform a software update.
Software update Instructions
Madoka Assistant app "13.3.2Software update with
app"on page17
Updating tool "13.3.3Software update with
updating tool"on page18
13.3.2 Software update with app
To update the software with the app:
1Activate Bluetooth on the user interface, according to the
instructions set out in "To make a Bluetooth connection" on
page17.
2In the home screen of the app, tap the tile of the user interface
of which you want to update the software, and follow the
instruction from there.
INFORMATION
The Madoka Assistant app is available from Google Play
and the Apple Store.
INFORMATION
When it is the first time you connect a user interface to
your device, app and user interface initiate a numeric
comparison procedure. To successfully connect the user
interface to the app, follow the procedure.
After each successful connection to a mobile device, the
user interface automatically stores information about that
mobile device, this to facilitate future reconnection. This
information is called "bonding information".
When no bonding information is stored, (i.e. at first
connection, or after it got manually removed), you will have
to go through the numeric comparison procedure.
When bonding information is stored, you can connect the
user interface to the mobile device just by making the user
interface send out a Bluetooth signal and tapping the tile of
the user interface in the app. The user interface will then
connect to the mobile device automatically.
Bonding information gets stored automatically, and can be
removed manually. Remove the bonding information from
the user interface when you want to update the software
from another mobile device than the one the user interface
contains information about.
INFORMATION
To connect the user interface to the mobile device with
Bluetooth, and to perform a software update, it is required
that you stay close to the user interface (i.e. within
Bluetooth range).
To make a Bluetooth connection
Prerequisite: You have a mobile device on which the Madoka
Assistant app is installed and running.
Prerequisite: On that mobile device, Bluetooth is turned ON.
Prerequisite: You are close to the user interface.
1From the home screen, press and keep it pressed until you
enter the main menu.

Result:
Numeric comparison
5In the Madoka Assistant app, tap the tile of the user interface of
which you want to update the software.
Result: If it is the first time you make a connection, or when
bonding information was removed, the operating system of your
mobile device sends out a pairing request, including a numeric
string.
Result: The user interface displays a numeric string, for
comparison with that of the pairing request.
6In the app, accept the pairing request.
7On the user interface, press to confirm the numeric string.
Result: The user interface and the mobile device are connected via
Bluetooth.
8To update the software, follow the instructions from the app.
To terminate the Bluetooth connection
1From the home screen, press and keep it pressed until you
enter the main menu.
2Use and to navigate to the Bluetooth menu.
